You are hooked up to an EEG; think of blue; now green.
Our memories may be kinda-sorta retrieved electronically. We do not know where exactly.
We know that memory is stored in the brain. And there is evidence that leads science to agree to the possibilty that all of our trillion or more cells store memory. What wew do not know is whether memory is stored beyond our phyical selves.
This book will be an experiment. We are not attempting to prove anything. This is not a religious search for proof of anything. We will begin with an idea which we will treat as a premise; What is there to learn about the acquisition of knowledge if we agree that there is memory that exists beyond the physical.
